3. Easter Island Easter Island is the south-easternmost of the Pacific Islands. It is small, isolated, and remote.

4. Geography Roughly triangular in shape has 3 major volcanoes.

5. It is barren and has few trees. NASA image created by Jesse Allen, Earth Observatory. Landsat 7 image collected January 3, 2001.

6. Where did the Easter Islanders come from The Pacific Islands were settle by a dispersal from Africa, in a route that runs along the south of Asia through Melanesia, then to Australia and Micronesia.

7. Settlement of the Pacific Islands 1000 B.C. 600 A.D. 500 B.C. 600 A.D. 1200 A.D. 800 A.D. 900 A.D. The Pacific Islands were settled from the northwest, probably from Asia and Melanesia, in a series of waves in easterly, then northerly (Hawaii) and southerly (New Zealand) directions

8. Organized Settlement • Easter Island was the last of Pacific Islands to be settled. • Evidence suggests that the settlement was well organized. • bones in middens (garbage dumps) show that animal and plant foodstuffs, not native to Easter Island, were amongst the earliest sources of nutrition • suggests that the settlers brought these items with them in a well organized manner.

9. Isolation • After settlement Easter Island remained isolated, and a society with roots from Micronesia, but with unique traditions arose. • Stone tools (made out of rock unique to particular Islands) are found throughout the south Pacific, suggesting trade between the Islands. • “But no stone of Easter Island has been found on any other island or vice versa.” This suggests that Easter Island society was effectively isolated.

10. Thriving Population • Evidence suggests that Easter Island had a large and rich thriving society. • Many house foundations (enough for 15-20K people) • Agricultural Intensification (large composting pits, water dams, stone chicken houses, stone windbreaks) suggests a lot of food was needed and available. • Society was broken into 11-12 territories or clans, not likely with a smaller population.

11. Moai and Ahu • Easter Island has hundreds of stone platforms (ahu) that support large statues (moai). • 13-32 feet tall • 10-87 tons in weight • One basic style, but made of different kinds of stone

12. A statue based economy • Constructed in 3 waves 1100 A.D. • Statues grew larger, more elaborate, and less human-like as time went by. • Economy centered around statue building • Many roads • Clan based niches in statue production • Food production concentrated to free up labor for statue construction

13. Why all the statues? • The stone on Easter Island is the best carving stone in the Pacific • Society was isolated, so the energy expended in other Pacific societies (trading, raiding, exploration, and colonization) was directed inward • Chiefs got stature not by inter-island interaction but by competing for status by a game of statue one-upman-ship • Later ones had a pukao, or large stone “hat” • Clan based society, let each clan “specialize” so while each group had a monopoly on some item, trade between groups was the norm.

15. How were they moved? • Theorist: Thor Heyerdahl • sledge • Theorist: Pavel Pavel • walked • Theorist: Charles Love • upright roll • Theorist: Jo Anne Van Tilburg • horizontal roll • Most rely on wood and logs • http://www.pbs.org/wgbh/nova/easter/move/past.html

16. How were they raised? • Transport, Raising, and Food Production issues suggest that many trees were cut down to provide for statue production and to clear land for food production. • When re-discovered in the early 1700’s there were no trees on Easter Island • Did Deforestation lead to the collapse?

17. An Abrupt End • Statue building, and the complex Easter Island society ended abruptly about 1600 A.D. • Incomplete statues still embedded in quarry • Total number of moai on Easter Island: 887 • Total number of maoi that were successfully transported to their final ahu locations: 288 (32% of 887) • Total number of moai still in the Rano Raraku quarry: 397 (45%) • Total number of moai lying 'in transit' outside of the Rano Raraku quarry: 92 (10%) • Stone carving tools left to lie • Chicken houses abandoned • Roads left in disrepair • What happened?

18. Collapse • Forests Gone • No trees on island when discovered by Europeans • Pollen analysis shows that indigenous palm trees were grown in the time of early settlers • large areas given over to food production (upland farms) • Food supply limited • upland farms abandoned • midden analysis shows large game birds disappeared • Large fish, porpoise, and seal bones also disappeared (no trees, no canoes, no deep water fishing) • Fuel supply limited • carbon tested early fires were trees, later fires were grasses • Erosion • soil eroded from base of statues, • Unrest • In the last days statues of rival clans were torn down, cannabilism

19. 5 point framework analysis • Damage to the environment • definitely yes • Climate change • a precipitating event that tipped the scales? • Hostile neighbors • no, isolation • Decreased support by friendly neighbors • no, isolation and no signs of trade • The society’s responses to its own problems • status instead of survival?

20. Presenting a chapter • Background • Where is it? (geography) • History • Context of society (how was it organized) • Interactions with other societies • What was it like at its peak? • What happened • broad picture • precipitating events • are there competing theories? • Diamond five point analysis • any critiques or other views

21. Details • Use graphs, pictures, visuals • include source below pictures/graphics if available • Give evidence (support your claims) • results of experiments • observations • facts and figures • Go beyond the chapter • research • ideas of others • Tell a coherent story

22. Presentation Guidelines • A presentation is a tool that helps you explain to others what you have done. • Most information is in your verbal comments. The slides gives you something to refer to, and reminds you of important points. • Keep visuals simple and uncluttered • Restrict text to 4-8 lines per page. • Use color and font changes to carry a message (e.g. related concepts or experimental results in the same colors), not arbitrarily and not too many. • Use LARGE fonts. • Use graphics rather than words on slides where possible. • Putting keywords/ideas on slide not only helps audience, but can help you remember presentation points.

23. Bad/Good Apples Essays • Great reflections on the issue of behavior in groups • Unfortunately, many writing errors in some essays • Bad/Good Types: Personality vs. Behaviors? • Experimental conditions vs. your experiences • Accuracy of statements

24. Group Activity • The nature of good leadership • What makes a good leader? • Everyone should voice their opinion • The causes of bad apple behavior (jerk, slacker, pessimist) • What underlies people acting in these ways? • Everyone should voice their opinion

25. In Mentor Session • Peer review of Collapse Papers • Verification of H: drive storage • Writing Logs
